Abstract (en)

[origin: US2014021391A1] Apparatus, including a diaphragm valve, is provided featuring a valve body, a diaphragm, a pressure ring, and at least one elastomeric member. The valve body may include a circumferential flange. The diaphragm may include a circumferential gasket portion configured to be seated on the circumferential flange so as to form a joint between the valve body and the diaphragm. The pressure ring may include concentric fluctuations, and may be configured to apply a sealing force against the joint so that the concentric fluctuations prevent radial movement of the circumferential gasket portion and the circumferential flange. The elastomeric member may be configured to respond to a compressive force and provide a substantially constant sealing force, transmitted through the pressure ring, regardless of small variations in the thickness or material dimensions of the circumferential gasket portion caused by temperature fluctuation or material flow and age.
